Example Code

import typer

def main(name: str):
    typer.echo(f'Hello {name}')


if __name__ == '__main__':
    typer.run(main)

Description

• run python typer_script.py
• On the typer.run() call: AttributeError: 'click.utils' has no attribute '_expand_args'

I was on typer version 0.6.1 and click version 7.1.2 (which meets the requirements for typer 0.6.1)

I updated to click version 8.0.4 and it's ok now.

In typer.core:190 you call click.utils._expand_args, but this was only added in click major version 8 from what I can tell.

Is there any update on this?

In the meantime, you can just add something along the lines of
click>=8.0.0,<9.0.0
to your requirements.txt, setup.py, etc. depending on your use-case.

I opened a PR and hopefully @tiangolo can see this at some point even though it seems to only be affecting a few of us.

I wouldn't care that much except for the fact that CLIs are generally going to be installed outside of a virtualenv and other libraries may have previously installed a lower version (like what I ran into).
